Northwestern Congolian Lowland Forests
The Northwestern Congolian lowland forests is a tropical moist broadleaf forest ecoregion that spans Cameroon, Gabon, the Republic of Congo, the Central African Republic and a minuscule part of the Democratic Republic of the Congo. It forms part of the larger Congolian rainforests region in Central Africa. The region is noteworthy for very high levels of species richness and endemism. It is home to a core population of the critically endangered Western lowland gorilla ( Gorilla gorilla gorilla). There are also large populations of forest elephants. Location and description The ecoregion is located in western central Africa, across the meeting of Cameroon, Gabon, Republic of Congo, and the Central African Republic (CAR). It stretches 500 km west-to-east and 700 km north-to south, set back 250 km from the Gulf of Guinea. Mean elevation is 530 meters, ranging from 79 meters to 1,451 meters. The highest areas are in the Chaillu Mountains of south Gabon and the Republic of Congo i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dzanga-Sangha Special Reserve
The Dzanga-Sangha Special Reserve (also known as Dzanga-Sangha Forest Reserve, or Dzanga-Sangha Forest Special Reserve, Dzanga-Sangha Baï, or Dzanga-Sangha Special Forest Reserve) is a protected reserve of southwestern Central African Republic. It was established in 1990 and covers 6865.54 km2. It is one of several areas within the Dzanga-Sangha Complex of Protected Areas (DSCPA), each within its own protective status and along with Lobéké National Park in Cameroon and Nouabalé-Ndoki National Park in Republic of Congo, it is part of the Sangha Trinational Landscape. Other areas within the DSCPA include the Dzanga Ndoki National Park which has two sectors, the Dzanga park and the Ndoki park. A conference of the Ministers of Forests of Central African Forest Commission (COMIFAC) had resolved to establish within the Congo basin, the Sangha River Tri-national Protected area (STN) encompassing these three parks. The forest special reserve is operated by the Central Africa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorilla Gorilla Gorilla
The western lowland gorilla (''Gorilla gorilla gorilla'') is one of two Critically Endangered subspecies of the western gorilla (''Gorilla gorilla'') that lives in montane, primary and secondary forest and lowland swampland in central Africa in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. It is the nominate subspecies of the western gorilla, and the smallest of the four gorilla subspecies. The western lowland gorilla is the only subspecies kept in zoos with the exception of Amahoro, a female eastern lowland gorilla at Antwerp Zoo, and a few mountain gorillas kept captive in the Democratic Republic of the Congo. Description The western lowland gorilla is the smallest subspecies of gorilla but still has exceptional size and strength. This species of gorillas exhibits pronounced sexual dimorphism. They possess no tails and have jet black skin along with coarse black hair that covers their enti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pan Troglodytes
The chimpanzee (''Pan troglodytes''), also known as simply the chimp, is a species of great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing for males and for females and standing . The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives in a ...

Mandrillus Sphinx
The mandrill (''Mandrillus sphinx'') is a large Old World monkey native to west central Africa. It is one of the most colorful mammals in the world, with red and blue skin on its face and posterior. The species is sexually dimorphic, as males have a larger body, longer canine teeth and brighter coloring. Its closest living relative is the drill with which it shares the genus ''Mandrillus''. Both species were traditionally thought to be baboons, but further evidence has shown that they are more closely related to white-eyelid mangabeys. Mandrills mainly live in tropical rainforests but will also travel across savannas. They are active during the day and spend most of their time on the ground. Their preferred foods are fruit and seeds, but mandrills will consume leaves, piths, mushrooms, and animals from insects to juvenile antelope. Mandrills live in large, stable groups known as "hordes" which can number in the hundreds. Females form the core of these groups, while adult male ...

Raffia Palm
Raffia palms (''Raphia'') are a genus of about twenty species of palms native to tropical regions of Africa, and especially Madagascar, with one species (''R. taedigera'') also occurring in Central and South America. ''R. taedigera'' is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods". They grow up to tall and are remarkable for their compound pinnate leaves, the longest in the plant kingdom; leaves of ''R. regalis'' up to long and wide are known. The plants are monocarpic, meaning that they flower once and then die after the seeds are mature. Some species have individual stems which die after fruiting, but have a root system which remains alive and sends up new stems which fruit. Cultivation and uses Fiber Raffia fiber is produced from the membrane on the underside of the leaf fronds. The membrane is taken off to create a long thin fiber, which can be rolled together for added ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbertiodendron Dewevrei
''Gilbertiodendron dewevrei'' is a species of tree in the family Fabaceae, native to tropical rain forests in Central Africa. It is often the dominant tree species of the Guineo-Congolian rainforest. The timber is traded as ''limbali'', and is used for construction, flooring and railway sleepers. It is also used for making boats, furniture, tool handles and joinery and for making charcoal. Description ''Gilbertiodendron dewevrei'' is a large evergreen tree, reaching a height of up to . The crown is dense and allows little light through. The unbuttressed trunk is cylindrical, with a diameter of up to or more, the lower half usually being devoid of branches. The bark is rough, greyish-brown or yellowish brown, peeling off in large flakes. The leaves are pendulous and leathery, the underside being covered with papillae, and they often have a few glands near the margins. They are alternate and pinnate with two to five pairs of leaflets. Each leaflet is ovate or elliptical, the lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pericopsis Elata
''Pericopsis elata'' is a species of flowering plant in the family ''Fabaceae'' and is known by the common names African teak, afromosia, afrormosia, kokrodua and assamela. Description The species grows to 30-45m tall with a trunk of 1–1.8m in diameter. Annual diameter increases between unlogged and logged areas have been shown to be similar. It is a deciduous species that flowers at the end of the main dry season. The minimum trunk diameter for reproduction is given as 32 cm, while that for effective flowering is 37 cm. The fruit take 7 months to mature. Despite its relatively small diameter, trees can live to be over 400 years old. Range The species is native to moist, semi-deciduous forests in Cameroon, Republic of the Congo, DRC, Ivory Coast, Ghana, and Nigeria. Up until the mid 20th century, the tree was commonly found in its native range. However, after its wood was introduced to world markets in 1948, its range quickly diminished. It can no longer be found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentaclethra
''Pentaclethra'' is a small genus of trees from the tropics. They are flowering plants in the family Fabaceae. They belong to the mimosoid clade of the subfamily Caesalpinioideae. The name ''Pentaclethra'' is derived from Ancient Greek, ''penta'' meaning 'five', and ''cleithro'' meaning 'bolt', which alludes to the five imbricate sepals and five petals joined at the base, characteristic of this genus. Species ''Pentaclethra'' is a small genus with three species. It is considered basal to the mimosoid clade. One species, ''P. macroloba'', occurs in the American tropics. This is the dominant tree in certain seasonal swamp forests in coastal areas of Atlantic Panama. The other two species occur in Africa. ''Pentaclethra,'' popularly known as ''ugba (''raw oil bean seeds'')'' in Africa, has great nutritional value. Proximate analysis of raw oil bean seed reveals that it is composed of proteins (36–42%), lipids (43–47%) and carbohydrates (4–17%) The high content of the esse ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Monsoon Climate
An area of tropical monsoon climate (occasionally known as a sub-equatorial, tropical wet climate or a tropical monsoon and trade-wind littoral climate) is a tropical climate sub-type that corresponds to the Köppen climate classification category ''Am''. Tropical monsoon climates have monthly mean temperatures above in every month of the year and a dry season. The tropical monsoon climate is the intermediate climate between the wet Af (or tropical rainforest climate) and the drier Aw (or tropical savanna climate). A tropical monsoon climate's driest month has on average less than 60 mm, but more than 100-\left(\frac\right). This is in direct contrast to a tropical savanna climate, whose driest month has less than 60 mm of precipitation and also less than 100-\left(\frac\right) of average monthly precipitation. In essence, a tropical monsoon climate tends to either have more rainfall than a tropical savanna climate or have less pronounced dry seasons. A tropical monsoon ...
